UNITED STATES PATENT OFFICE.

ROBERT HAMILTON, OF FRANKLIN, INDIANA.

IMPROVED ROAD-SCRAPER.

Specification forming part of Letters Patent N0. 86,223, datedJanuary-26, 1869.

To all whom it may concern:

Be it known that I, ROBERT HAMILTON, of Franklin, Johnson county,Indiana, have invented a new and useful Road-Scraper; and I herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had tothe accompanying drawings, making part ofthis invention.

This is an improvement in the class of roadscrapers whose scoop isadapted to be drawn along the surface of the ground in the operation ofgrading and leveling roads, dto.; and my invention consists in anarrangement of shovel or scoop which, when in theact of gathering rocksor earth, is upheld and guided by a peculiarly-formed shoe or soleplate, the load thus acquired being capable of being instantaneouslytilted or dumped when brought to the proper place for that purpose.

"Figure 1 is perspective view of my improvement. Fig. 2 is a sideelevation of the same. Fig. 3 is a similar elevation of the operativeparts in their position of dumping or discharging the load. Y

A, B, and C C represent respectively the sheth, beam, and handlesconstituting the Woodenportion of a road-scraper.

The scoop or shovel D, instead of being rig idly attached to the shethor standard, is hinged thereto at about the middle of its rear portionby means of a T-bar, E, made fast to the front side of the sheth.

F is a spring-latch, which, engaging over the top edge of the shovel,holds it to its lling position until released by means of the foot, asshown in Fig. 3.

` A chain, G, extending from the beam to the upper part of the shovel,serves to limit its playin the act of dumping, and to hold it in asuitable position for leveling the loose earth."

Attached to the bottom of the sheth'is a shoe, H, ot' iron or steel,adapted to restand slide upon the ground behind the scoop. The said shoeis so attached as to rest horizontally upon that portion of the groundwhich vhas been leveled by the scraper, and assists to hold theimplement level and to adire.:t course.

The said shoe also assists the operator in holding the scoop clear ofthe ground for conveyance of its load of earth to the place ot' de-,posit The scoop, when full, beingronducted to the desired 611, theoperator releases the scoop by depressing the spring-latch with hisfoot, as shown in Fig. 3, and slightly raises the handles, whereupon theadvance of the implement serves to tilt the scoopin the manner shown.

I claim herein :is new andot' myinvention- The described arrangement ofscoop D, hinge E, springlatch F, chain G, and shoe H, for the purposeset forth.

In testimony ot' which invention I hereunto srt my hand.

ROBERT HAMILTON.
